A system and method displays a safe route from a location to a destination that avoids one or more hazards detected, such as a fire or a gas leak.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of providing for display, a map of at least a portion of a facility, comprising: receiving at least one indication of at least one hazardous condition; identifying the map of the at least the portion of the facility, the map showing at least one path, each path corresponding to a plurality of links, each link corresponding to a plurality of nodes, each node corresponding to a point at least near a path in the facility, the identifying being responsive to the at least one indication of the at least one hazardous condition, and to a plurality of metrics, each metric corresponding to one of the plurality of links; and providing for display the map identified.
2. The method of claim 1 wherein the identifying the map step comprises identifying a map showing a route that avoids at least one of the at least one hazardous condition.
3. The method of claim 2 wherein the identifying the map step comprises selecting a map from a plurality of maps.
4. The method of claim 2 wherein at least one of the plurality of metrics comprises an amount of time it takes to traverse the corresponding link.
5. The method of claim 4 wherein at least one of the plurality of metrics comprises a capacity of at least a part of the path the corresponding link.
6. The method of claim 4 wherein the destination is an exit from an area in which at least one of the at least one hazards has occurred.
7. The method of claim 2 wherein the map comprises at least one landmark in a facility.
8. The method of claim 6 wherein the facility is a semiconductor manufacturing facility.
9. The method of claim 1 wherein the map is identified additionally responsive to at least one location.
10. The method of claim 9 wherein the location comprises an exit of an area in which at least one of the at least one hazards has occurred.
11. The method of claim 9 wherein the location comprises a starting location.
12. The method of claim 11 wherein the starting location is moveable.
13. The method of claim 1 wherein the providing for display step comprises providing the map for display on a device having a fixed location.
14. The method of claim 13 wherein the identifying the map step is additionally responsive to the fixed location of the device.
15. The method of claim 1 wherein the providing for display step comprises wirelessly transmitting at least one selected from: a. the map; and b. the at least one indication.
16. The method of claim 1 additionally comprising specifying the display from a plurality of displays.
17. The method of claim 1 , additionally comprising displaying additional information.
18. The method of claim 17 wherein the additional information comprises information about at least one chemical in an area near the at least one hazardous condition.
19. The method of claim 18 wherein the additional information comprises information regarding work in process in an area near the hazardous condition.
20. The method of claim 18 wherein the additional information comprises permit information about at least one area near the hazardous condition.
21. The method of claim 1 additionally comprising forwarding a communication from a first party near a first location at which the map is displayed, to a second party at a second location different from the first location.
22. The method of claim 1 wherein the facility comprises at least one tunnel.
23. A computer program product comprising a computer useable medium having computer readable program code embodied therein for providing for display a map of at least a portion of a facility, the computer program product comprising computer readable program code devices configured to cause a computer system to: receive at least one indication of at least one hazardous condition; identify the map of the at least the portion of the facility, the map showing at least one path, each path corresponding to a plurality of links, each link corresponding to a plurality of nodes, each node corresponding to a point at least near a path in the facility, the computer readable program code devices configured to cause the computer system to identify being responsive to the at least one indication of the at least one hazardous condition, and to a plurality of metrics, each metric corresponding to one of the plurality of links; and provide for display the map identified.
24. A system for identifying a map of at least a portion of a facility, the system comprising: a detector having at least one input for receiving at least one sensor state, the detector for providing at an output at least one indication of a hazardous condition responsive to the at least one sensor state; a map identifier having an input coupled to the detector input for receiving the at least one indication of at least one hazardous condition, the map identifier for identifying the map of the at least the portion of the facility, the map showing at least one path, each path corresponding to a plurality of links, each link corresponding to a plurality of nodes, each node corresponding to a point at least near a path in the facility, the map identifier identifying the map responsive to the at least one indication of the at least one hazardous condition and providing at an output at least one indication of the map identified, and to a plurality of metrics, each metric corresponding to one of the plurality of links; and a map displayer having an input coupled to the map identifier for receiving the at least one indication of the map identified, and for providing for display via an output a map corresponding to the map identifier received at the map displayer input.
